All three contracting methodologies suggested for solutions-based buying permit competition among a competitive pool of limited size. In the case of FSS MAS contracting, agencies use the "special ordering procedures" for services. These procedures permit the team to conduct market research and select a number of contractors for the competition. Those contractors are then sent a Request for Quotation, Request for Solutions, or some similar solicitation document (which includes the PWS or SOO) to which they respond. Or the contracting office can post a notice on e-Buy. In either case, the government team defines the competitive pool.

When using existing GWACs or MACs, the competitive pool is set by the initial competition that resulted in contract awards. Under the provisions in the GWAC or MAC, agencies follow the "fair opportunity" competitive processes to further limit the competitive pool and then to determine which

contractor will be awarded the task or delivery order. The existing contract vehicle sets the competitive pool.

The process is more complicated if an agency chooses to use negotiated procurement methods under the provisions in FAR Part 15, but thanks to acquisition reform techniques, it is possible. The key is the use of the advisory multi-step process (authorized by FAR 15.202). Because no respondent is precluded from competing, this is not a competitive range determination--the latter can also be used. So in this contracting methodology, the agency uses the FAR 15 advisory multi-step process and competitive range determinations to define the competitive pool.

The agency's selection of a contracting methodology can affect the cost and time required to compete, as well as the degree of competition. It's the quality of the competition that is most significant, not the number of competitors.
